Newbie questions

[Gustavo Sverzut Barbieri]

Hello,

I'm a newbie to ACPI (just bought a
desknote(www.desknote.biz) laptop that ships w/ that).
I'm trying to use ACPI withou success. The kernel
2.5.{29,30} don't even compile (error with: save_flags
and restore_flags, listed below).

I'm using red hat 2.4.18-3 recompiled right now, that
looks too old (I tried 2.5.24 before, the /proc/acpi
subsys gives more info)

I got acpid, but I got nothing more than mapping the
buttons (power and lid) to run what I desire. I wanna
know how I put it to sleep (suspend, and how to come
back)

Best regards.

Gustavo

drivers/acpi/system.c lacks the inclusion of linux/interrupt.h.

So add
#include <linux/interrupt.h>
to drivers/acpi/system.c and it should build.

Don't really know about but Pavel Machek is working on software suspend for
2.5 kernels. Tried it every now and then but it's not 100% working yet since
it's still under development as the whole 2.5 kernel is.
Better is you stickt to 2.4 kernels.
To get acpid work with 2.5 kernels you need a patch for acpid to get it to 
work with latest acpi.

Axel
